WASHING- MACHINE.

SPECIFICATION forrning part of Letters Patent No. 653,429, dated July 10, 1900.

Application filed October 10, 1898. Serial No. 693,098. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK H. WIARD, a citizen of the United States, residin g at East Avon, in the county of Livingston and State of New York, have invented new and useful Improvements inWVashing-Machinespf which the following is a specification.

This invention relates more particularly to that class of washing-machines which comprise an oscillating tub or vessel provided in its bottom with a roughened surface or rubber, an upper oscillating rubber arranged in the tub and cooperating with the rubber of the tub, an upright hand-lever for oscillating the rubbers in opposite directions, and a yoke or cross-bar carrying the upper rubber and pivoted to a standard at one side of the tub and having its free end detachably secured to a bracketor support at the opposite side of. the tub, so that upon releasing the detachable end of the yoke the'same can be raised or swung out of the way for placing the clothes in the tub and removing them.

One of the objects of my invention is to provide improved means for pivoting the yoke to the frame in such manner that the yoke and the upper rubber carried thereby can be readily removedfrom the machine, so that the latter can be more conveniently carried from place to place.

In the accompanying drawings, consisting of two sheets, Figure l is a sectional elevation of my improved Washing-machine,showing the parts in position for use. Fig. 2 is a top plan view thereof. Fig. 3 is a fragmentary sectional elevation of the machine, showing the yoke unlocked and retracted to clear the Wash-wringer preparatory to raising the yoke. Fig. 4 is an enlarged side elevation of the pivotal connection between the yoke and its support. Fig. 5 is an enlarged longitudinal section of the free end of the yoke and its supporting-bracket, showing the fastening for securing the yoke to the bracket. Fig. 6 is a transverse vertical section in line 6 6, Fig. 5.

Like letters of reference refer to like parts in the several figures.

The stationary supporting-frame of the machine is composed of uprights A A,'having feet A and upper and lower cross-pieces or boards A A connecting the uprights, the

upper cross-piece extending laterally beyond the short upright A and the other upright A extending some distance above said upper cross-piece.

; B is the tub or vessel for the clothes,which is supported upon a rotary or oscillating platform C, mounted on the upper end of an upright shaft D. The tubis preferably removably secured to this platform by radial pins (2, arranged on diametrically-opposite sides of the tub and engaging with bifurcated lugs e, secured to the projecting arms of the platform, as shown in the drawings, or by any other suitable means. The upright shaft D is preferably supported at its lower end in a ball bearing of any suitable construction mounted on the lower cross piece A and turns near its upper end in a suit-able ball or roller bearing mounted on the upper crosspiece A to reduce the friction to aminimum.

E designates the raised ribs or bars secured to the inner side of the tub-bottom and forming, with said bottom, the lower rubber of the machine.

F is the upper rubber, arranged in the tub in close proximity to the rubber thereof and having ribs on its under side, in a Well-known manner. This upperrubber is secured to the lower end of an upright shaft G, which is suspended from the movable yoke or cross-bar H, so that the same is raised and lowered with the yoke. The shaft G is square, as shown in Figs. 1 and 2, and free to slide vertically in a bearing-sleeve g, which is provided with a square bore to fit the shaft and which is journaled in the yoke in the customary manner to allow the shaft to oscillate in the yoke. The upper and lower rubbers are oscillated in opposite directions by any suitable means,

the devices shown in the drawings for this purpose consisting of an upright hand-lever I, pivoted between its ends to a standard 1, and armsjj, secured to the tub-platform and the oscillating bearing-sleeve g, respectively, and connected with the upper and lower arms of the hand-lever by links j j The standard I is secured to the overhanging portion of the upper cross-piece A I is a standard mounted on the cross-piece A between the tub B and the lever-standard I and stiffened by a brace 1 The yoke is pivotally mounted at one end on the standard I in such a manner that the yoke is free to slide outwardly on the same as well as swing upwardly and downwardly thereon. For this purpose the standard is provided at its upper end with a pair of elongated bearings or horizontally-slotted lugs k, arranged side by side, and the yoke is provided with depending arms Z, having laterally-projecting pivots or studs Z, which engage in the slots of the lugs 7;, whereby the yoke is hinged to the standard and at the same time free to slide lengthwise thereon. The slotted lugs 70 are provided in their upper sides with openings 7t for disengaging the pivots of the yoke from the lugs when it is desired to remove the yoke from the machine. The free end of the yoke is detaehably secured to a bracket m, projecting inwardly from an upright board or support N, which is arranged at the upper end of the upright A and to which the wash-wringer is clamped, as shown by dotted lines in Figs. 1 and 2. This bracket is preferably constructed in the form of a seat or socket which is open at its top and its inner end, as shown in Figs. 3 and 5, and the free end of the yoke is detachably locked in the bracket by any suitable fastening. The preferred fastening,which is shown in the drawings, consists of an upright pawl or latch o, pivoted by a transverse pin in a longitudinal slot or recess 0, formed in the yoke, and provided at its projecting lower end with a hook or shoulder 0 adapted to pass through a longitudinal slot 17, formed in the depressed bottom of the bracket in, and to interlock with the inner edge thereof, as shown in Fig. 5. The latch is locked in this position by a horizontally-swinging cam or wedge q, pivoted to the upper side of the yoke and engaging under a nose q, formed at the projecting upper end of the latch on the inner side thereof. This wedge prevents the lower arm of the latch from swinging outwardly and becoming disengaged from the bracket. Upon moving the wedge aside, so as to clear the nose of the latch, the latter is unlocked, and upon pushing the upper arm, of the latch inwardly its hook is disengaged from the bracket m, releasing the free end of the yoke therefrom.

WVhen the free end of the yoke is attached to the the wringer-board N,the wringer overhangs the same, as shown by dotted lines in Fig. 1, and when it is desired to remove the upper rubber from the tub for removing or introducing clothes the yoke is unlocked from the bracket of the wringer board and slid lengthwise away from said bracket, so that its free end clears the wringer, when the yoke can be swung upwardly withoutthe necessity of removing the wringer from the tub. In order to detach the yoke from the machine, it is only necessary to bring its pivot-pins Z opposite the apertures 7:, of the slotted lugs and withdraw the same from the lugs. By this construction the yoke can-be quickly detached without the use of a wrench or other tools. The ready detachability of the yoke is a desirable feature in machines of this kind in carrying the machine about. The same is clumsy and awkward when the yoke remains attached to the machine, and, furthermore, when the yoke is readily detachable the upper rubber, which becomes watersoaked in use, can be removed from the machine and stored in a cool place after completin g the washi n g, thereby preventing warping or checking of the same, which is liable to occur when the rubber is stored inawarm place, and also avoiding the necessity of carrying the whole machine for this purpose.

I claim as my invention 1. The combination with the oscillating tub and the stationary supporting-frame of the machine having standards arranged on opposite sides of the tub, of a horizontally-slotted lug or bearing arranged at the upper end of one of said standards and provided between its ends with an opening which communicates with the slot of the lug, and a Verticallyswinging yoke or cross-bar carrying a rubber and provided at one end with a horizontal pivot which is arranged in said slotted lug and which is adapted to be inserted and removed through the opening thereof, substantially as set forth.

2. The combination with the stationary frame of the machine and an oscillating tub or vessel, of standards or supports arranged on opposite sides of the tub,a bracket or'socket arranged on one of said standards and provided in its bottom with a slot or recess, a yoke or cross-bar carrying a rubber and pivoted at one end to one of said standards and having at its opposite end an upright latch pivoted to swing lengthwise of the yoke and provided below the yoke with a hook which interlocks with the opening of said bracket and means for retaining said latch in engagement with said bracket, substantially as set forth.

3. The combination with the stationary frame of the machine and an oscillating tub or vessel, of standards or supports arranged on opposite sides of the tub, a bracket or socket arranged on one of said standards and provided in its bottom with a slot or recess, a yoke or cross-bar carrying a rubber and pivoted at one end to one of said standards and having at its opposite end an upright latch pivoted to swing lengthwise of the yoke and provided above the yoke with a locking-nose and below the same with a hook which interlocks with the slot of said bracket, and a laterally-swinging locking cam or wedge pivoted to the upper side of the yoke and adapted to engage under the nose of the said latch, substantially as set forth.

\Vitness my hand this 27th day of September, 1898.
